Improvement and Harmonization of Montenegro BSHAP Earthquake
* Intensity data not given* Mm data not given* Reporting agency PDG* (Automatic) Declustering procedure on polygon* Mw given acc to L. Duni, N. Kuka, Sh. Kuka, A. Fundo, 2010 “Towards a new seismic hazardassessment of Albania”, Proceedings of XIV ECEE Ohrid,
Macedonia, T1- paper No1894.
National catalogue data*delivered by the beginning of BSHAP project
Mw 3.0 + events since 1970* delivered for Improvements
Statistics on 1970-2012 M 3.0+ sub-catalogue: No of Events: 1008
No of Main events: 413 No of Cluster events*: 595
1970-2012 Mw 3+ Subcatalogue is relevant for the investigation of completeness of smaller magnitude classes, J. Mihaljevic
Completness of magnitude class 3.0 < Mw < 3. 5(Cumulative No of events vs Year)
Completness of magnitude class 3.5 < Mw < 4.0
Completness of magnitude class 4.0 < Mw < 4.5
Completness of magnitude class 4.5 < Mw < 5.0
Investigation of completeness of higher magnitude classes (sipmple addition of latest data to MSO +3.5 catalogue provided in July 2010)
Completness of magnitude class 5.0 < Mw < 5.5
Completness of magnitude class 5.5 < Mw < 6.0, 6.0 < Mw < 6.5, 6.5< Mw < 7.0
• Available earthquake catalogue BSHAP _E catalogue (M. Herak): - mo 3.0, mmax 7.4
- time span [-510, 2009] y.- declustered- no magnitude type unification.
• National Mne catalogue refers to 1440 A.D., while the neighboring Albanian and Croatian catalogues originate from times B.C.
• Data completeness to be investigated on extract/subcatalogue of BSHAP_E catalog for narrow Montenegro territory: This choice was set to preserve the rate of known large earthquakes for Montenegro itself. Shortcoming of method is that number of available earthquake data is smaller.
• Magnitude classes: 0.5 and 0.2 magnitude increment• Completeness investigated for each magnitude class
Previous Investigation on data completeness influence to final seismic hazard results, J. Mihaljevic
NATO SfP 984374 PROJECT Improvements in the Harmonized Seismic Hazard Maps for the Western Balkan
Countries Sensibility Analysis - Case Study Montenegro, J. Mihaljevic
Approach National - (a) Harmonized / Regional – (b) (c)
Catalogue BSHAP-E version ranging from 1440 A.D
More precise completeness level
BSHAP-E version ranging from -510 B.C.Not so uniform completeness over the region
Seismotectonic Precise for Mne,
General for the Influence areaPrecise and harmonized for the region
Sesimotectonic models:
(a) Montenegro case study,(b) Corresponding section of BSHAP seismoteconic model prepared for preliminary hazard assessment, Zagreb workshop( c) Corresponding section of BSHAP Final BSHAP sesmotectonic model.
